Description:
------------
Set oci8.statement_cache_size = 30 in php.ini
Set open_cursors = 30 in Oracle.
Run the script and die on the 31st cursor:

Cursor 30 executed

Warning: oci_execute(): ORA-01000: maximum open cursors exceeded in /home/dke/work/cursors/php/t2 on line 17



Test script:
---------------
#!/bin/env php
<?php
// Create connection to Oracle
$cx = oci_connect("/", "", "TST", null, OCI_CRED_EXT );
if (!$cx) {
   $m = oci_error();
   echo $m['message'], "\n";
   exit;
}

$st = oci_parse($cx, "ALTER SESSION SET tracefile_identifier='T2' SQL_TRACE= TRUE");
oci_execute( $st );
$qry = "select 1 + %d from dual";

for ($i=1; $i<=31; $i++) {
   $st = oci_parse($cx, sprintf( $qry, $i) );
   oci_execute($st, OCI_DEFAULT);
   oci_fetch_all($st, $res);
   oci_free_statement( $st );
   printf( "Cursor %d executed\n", $i );
}

// Close the Oracle connection
oci_close($cx);
?>


Expected result:
----------------
I expect not to die on ORA-1000. I'm properly closing my cursors, after all.
There should be a sanity check on oci8.statement_cache_size that ensures it is strictly inferior to the Oracle parameter open_cursors.

Actual result:
--------------
Cursor 30 executed

Warning: oci_execute(): ORA-01000: maximum open cursors exceeded in /home/dke/work/cursors/php/t2 on line 17
